What You Can Expect

Actun Tunichil Muknal (ATM) Caves from San Ignacio

Explore ATM Cave in Belize!

Considered one of the best caves of Central America, Actun Tunichil Muknal has been feature by National Geographic, the Discovery Channel and the History Channel. Your guide will pick you up at your hotel in San Ignacio for the drive to ATM — a place where only Mayan priests and shamans could venture 1,000 years ago. Travel for 45 minutes along the Western Highway of Belize to Teakettle Village. It’s another 30-minute drive on a bumpy road south of the village to the Tapir Nature Reserve—a subtropical rainforest that receives at least 8 feet (2.4 meters) of rain per year.

Here, your experienced guide leads your group on an easy 45-minute hike to the cave. Walk along the bank of the Roaring River, which you’ll cross three times before arriving at the cave entrance, where a lovely pool awaits — especially refreshing on a sunny day. Depending on the time of arrival, you’ll eat lunch before or after your caving adventure.

To prepare your group to enter the cave, your guide provides a historical overview and safety briefing. After you’ve been outfitted with equipment and taught a variety of spelunking techniques, the real fun begins! The water passage allows you to splash and play as you wade through the water, which may come up to your ankles, knees, waist and even neck — sometimes requiring you to swim.

About five minutes into the cave, you’ll find your biggest challenge at the ‘breakdown’ — where slabs of rock form the passageway. Your guide will show your group how to go from one rock to the other and slide in between a couple of boulders. At one point, you’ll climb up to a ledge to enter one of the most attractive parts of the cave, where archeologists have recorded more than 1,000 pieces of pottery and 14 human sacrifices.

To explore this chamber, you’ll be required to remove your shoes (socks or bare feet are an option) in order to protect the natural surroundings, including impressive formations like rock columns, stalactites, stalagmites, citrines and flowstones. While exploring this living museum, your guide will share fascinating details about ancient Mayan rituals and ceremonies that once took place deep under the earth. You’ll learn how the Mayan priests took human offerings into the caves, displayed pots in symbolic ways and communicated with their gods.

After your spelunking adventure, your guide will transport you back to your hotel in San Ignacio.

Great tour that felt like a true adventure. You will have to wade through the river three times and then swim into the entrance of the cave. Depending on how the water is you may be in water that is as high as your neck. Go into this expecting to get wet from head to toe as well as having to squeeze through tight spaces in the cave.

Indiana Jones for a day. Physical workout but not overly demanding. Ruins are cool but visiting a sacrificial burial chamber with actual remains is one of the coolest things I've ever done. Our guide Edward was terrific, very knowledgable. Once in a lifetime activity worth every penny.

We enjoyed this tour. Our van was no frills broken handle, etc. but the guide was friendly and knowledgable. He customized the trip and made it more adventurous for us because the group was small 6 people and we were physically fit. It was amazing to be in the cave, knowing some of its history in the Mayan culture.
